Even the beginnings of the world of sweeping technology of the time make new brooms on large surfaces look old. The Stolzenberg Company, founded in 1889 as a brush factory, has been active in the development and production of hand-operated sweepers for over 40 years. In 1965, when the main pillar “carpet sweeper” had to give way to the booming market for household vacuum cleaners,
THE ROLLING DUSTPAN PRINCIPLE
A first step in the right direction
an attempt was made to develop an “enlarged carpet sweeper” for industrial cleaning. What was initially used for individual use soon found great interest from buyers and went into serial production as a result. The function of the first German sweepers: the so-called dustpan principle.
The problem with the dustpan principle
The sweeper roller, rear mounted in the direction of travel, rotates during forward motion against the direction of travel of the sweeper. When riding over the dirt, this must be under a rubber lip throughout in order to then be swept into the front-mounted dirt container, like a sort of dustpan. In practice, however, this first development step contains some problems.
